Isis 3 Application Documentation
Trims pixels outside of phase, incidence, and emission angles
Description
This program trims pixels outside of user specified phase, incidence and
emission angles. It is meant to work specifically on camera based cubes.
The phase angle is the angle between the sun vector to a pixel and the
instrument vector to the same pixel. The incidence angle is the angle
between the sun vector to a point and the normal at that point. The
emission angle is the angle between the instrument vector to a point and the
normal at that point.
If the instrument is directly between the point and the sun the phase,
incidence and emission angles are all zero. If the instrument is looking
down the normal and the sun is not then the phase, incidence and emission
angles are greater than 0 but less than or equal to 90. If any of the angles
is greater than 90 then the sun is not hitting the point or the instrument
can not see the point.
